A little bit of validation goes a long way in ensuring that our array is normalized for optimal performance within our upcoming neural network. Â
Validating array for optimal neural network performance
Getting ready
This section will require a bit of numpy magic using the numpy.stack() function.
How to do it...
The following steps walk through validating that our array has been normalized.
- Execute the following step to print the mean and standard deviation of array inputs:
print('standard deviation')
print(round(X[:,0].std(axis=0),0))
print('mean...
